To all whom it mayconcern .1

Be it knowngthat I, HARRY J. CRTNEB, acitizen of the UnitedStates,residing at Burlington, in the county, of ,Des Moines and Stateof-Iowa, have invented certain new and useful Improvements in Water-Motors, of which thefollowing is a specifi' cation. 7 4 I a The presentinvention relates to improvements in water. motors, and is designed toprovide a fluid motor of the reciprocating type that is facile andeiiicient in operation, is compact and durable, and being composed V ofcomparatively few parts is not liable to become deranged. The elementsof the com bineddevice are simple in construction and may be assembledquickly and with facility, and if necessary the motor may be. dismantledwith equal facility.

The invention consists in certain novel combinations and arrangements ofparts as hereinafter set forth and claimed.

In the accompanying drawings 1 have illustrated one complete example ofthe physical embodiment of my invention constructed according to thebest mode I have so far devised'for the practical application of theprinciples. V

Figure 1 is a vertical longitudinal sectional view of the working partsof the Fig. 2 is a similar View of the piston of the motor; Fig. 3 is atransverse vertical sectional view on line 3-3 of Fig. 2. Fig. 4 is asectional view of the pin valve.

The motor casing or cylinderl is closed at its left end by an integralhead 2, and is formed witha Water inlet 3 and exhaust or outlet 4; forwaste water. These openings are provided with suitable inlet hose andoutlet or waste hose forthe transmission of water to, and from thecylinder. The open end of the cylinder is closed'bya cap plate5 havingan integral packing cup 6m in which the gland 7 is threaded.

Within thecylinderthe piston ,8is adapt ed to reciprocate, and by meansof'its stem 9 will communicate power to be applied as desired. The stem9 is passed through the packed gland 7 and is threaded into the closedend 10 of the piston, the other end of the piston being open to form achamber 11 between the partition 01' head 12 of the piston and the head2 of the cylinder. As best seen in Fig. 3 the piston which iscylindrical in cross section is provided with a smaller concentricpartition 13 which forms a semiannular space or chamber llfbetween theseouter and inner walls of the piston, and the piston wall and partitionare fashioned'with ports 15 and 16 respectively in alinement asshown,the chamber 14: being bounded by longitudinal partitions 17 and18.

The concentric partition 13 provides a cylindrical valve casing orchamber 19 in which a hollow cylindrical valve 20 reciprocates. Thisvalve has a limited movement between the heads 10 and 12 of the hollowpiston and is carried bodily by the piston in its reciprocation. At oneside a port 21 is provided'and this port is of suiiicient dimensions toremain at all times and in all positionsin communication with thechamber 1.4, of the piston 8 through the port 16. Within the hollowvalve 20 a partition 22 is formed which furnishes a space 23, and ateachside of the partition a port as 24: and 25 is provided, "these ports andthe space 23 being positioned and adapted to register with an L-shapedport 26, a shorter port 27, or a radial port 28, the twoformer openinginto the cylinderand the latter opening into a space 29 at the upperside of the piston and between it and the wall of the cylinder 1.

. In Figs. 3 and ia pin valve 30is illustrated. This valve is acylindrical bar or pin and is movable in a cylindrical opening 31 thatextendsthe entire length of the piston. The pin valve is somewhat longerthan the piston and projects beyond the piston ends, while its undersideis cut away at 32 and 33 to form spaces that may alternately registerwith the short port 34- opening from the chamber 14 to the opening 31.Each of these spaces communicate with the interior of the chamber 19beyond the ends of the valve 20, one opening thereinto through theport35 and the other through port 36, these ports being so positionedthat water may flowtherethrough alternately and impinge against the endof the floating valve 20 and move it as will be understood. Thespaces 32and 33 have exhaust ports 37 and 38 respectively which communicate withthe exhaust chamber 29 to exhaust water from the rear of the pistonvalve 20, the port 38 being rric shown as registering with port 36 inFig. 4.

In the other position of the valve the port 37 registers with the port35, as will be un the right in Fig. 1.

chamber 14 through registering ports 16, 21 into the hollow valve 20.Port 25 is closed but the water is permitted to flow through ports 24and 26 to the rear of the piston and into its chamber 11 and forcing thepiston to ricd bodily to'the right in the hollow piston, it beingunderstood that'there is a water pressure at the rear of the valvethrough port 35. Vihen the piston reaches the end of'its strokeito theright, or rather just before it reaches the end of'the stroke, the pinor rod valve 30 strikesthe head 5 of the cylinder and the rod valve ismoved to the left from the position shown in Figs. 1, 2 and 4. Port 35of chamber 19 is now open to the exhaust space29 to drain Water from theleft end of the valve 20, and port 83 of the rod valve is open to port345 to receive water from chamber 1% and convey it through port 36 tothe right end of the valve 20, the exhaust port 38 now being covered.Water pressure throughthe port 36 forces the valve to the left closingport 26 and opening port 27 through port 25 to the interior of the valve20, and also opening eX- haust' from the left end of the cylinderthroughports'26, 23, 28, and chamber 29. The water now flows through theports 25, 27 to the right end of the cylinder and its pressure moves thepiston to the left, when the pinvalve is again reciprocated to. open andclose reverse ports to reciprocate the valve 20 to reverse'the flow ofwater and thus the piston is reciprocated.

Having thus fully described my invention,
